Involving Low-Pressure Plasma for Surface Pre-Treatment and Post Print Sintering of Silver Tracks on Polymer Substrates

A method of production conductive silver tracks on thermally sensitive polymer (BOPP) was offered, involving plasma for preprint polymer surface activation to enable better adhesion properties and postprint selective etching to reduce amounts of polymer and raise electroconductivity. Inkjet, spin coating, and roll-blade coating were the methods of application of silver nanoparticle inks. We report to achieve two magnitudes lower sheet resistance of silver thin film with no effect on polymer substrate. This method with little modification could be adopted for production of flexible electronics on highly thermally sensitive polymers.
